What are the principles of early pregnancy test strips?

Early pregnancy test strips are very common, and their use cannot be random. Women should choose according to whether they have signs of pregnancy, otherwise the early pregnancy test strips will be wasted. The use of early pregnancy test strips is not very complicated, and they can be easily learned. However, it should be noted that the test strips must be used correctly, so as not to affect the results. What is the principle of early pregnancy test strips?

Principle of early pregnancy test paper:

The detection reagent uses the principle of immunochromatographic double antibody sandwich method to make HCG detection test strips, which can measure HCG in urine samples within 3 minutes. During the test, when the urine sample is siphoned through the colloidal gold-labeled antibody, an antigen-antibody colloidal gold complex is formed. The complex continues to crawl and passes through the coated anti-HCGα subunit Mcab to form a double antibody sandwich colloidal gold complex, which appears as a color band at the coating line. The excess colloidal gold antibody continues to crawl and forms a colloidal gold immune complex with the sheep anti-mouse control line, which appears as a color band. The HCG colloidal gold test kit uses a double antibody sandwich one-step technology and colloidal gold as an indicator marker to detect the HCG concentration in urine to confirm whether a woman is pregnant. The test strip is a reliable indicator to assist clinical determination of pregnancy.

Human chorionic gonadotropin (HCG) is a glycoprotein hormone produced by the placenta of pregnant women. The early pregnancy test strips use double antibody sandwich one-step technology and colloidal gold as an indicator marker to detect the HCG concentration in urine to confirm whether a woman is pregnant.

After understanding the principles of early pregnancy test strips, you can use the test strips with confidence. If pregnancy is detected, women should go to the hospital for a comprehensive examination in time, so that they can have some understanding of their specific situation. At the same time, the doctor will also tell them what to do specifically. It is very important to protect the fetus in the early stages of pregnancy, otherwise miscarriage will occur.
